Since then, every time my transmission gets hot on the track, I have trouble shifting into first or reverse and have to double shift. I just ordered some Redline MT-90 and will see how it handles the higher temps. Since I'm in the South, the cold temps should not be a problem. In retrospect, I should never have changed from the BMW lifetime fluid in my car. I was not having any trouble, but just decided to be pre- emptive since I do so many track days.

(I am surprised you are asking the question, it seems like you already answered it through your research...) Because some think the ellipsoid/projectors look "cooler". The Free Forms are more efficient as distributing the light since the projector is less efficient but the Free Forms don't have the cool "eyeball" projector look. Both are better than the crappy DOT legal US headlights of course. The ellipsoids were the original E36 headlights in Europe (up to 9/94 I believe), the Free Forms didn't come around until later (after 9/94) as the technology evolved.

That's the type of fluid (D4 ATF) spec'd for your '98 M3/4 (and mine). I've used it in the tranny of my M3 since the first fluid change at ~30,000 miles. Car now has ~134,000 miles with about 8-10,000 of those miles track miles (approx 80 tracks days over 3 years). I've had absolutely no problems with it, changing the fluid at 30,000 mile intervals. YMMV. Just a data point, Jim Bassett - SF Bay Area, doesn't get that cold here either :-) 1998 M3/4 - Red Line fluids in engine & drivetrain 1993 325is #44 JP/A5 - Mobil 1 engine/Red Line drivetrain ------------------------------ Date: Wed, 24 Sep 2003 12:20:26 -0700 (PDT) From: Jason Knight <[EMAIL PROTECTED]> Subject: Re: [uuc] First time with Redline MTL I only have a handful of track days under my belt, but would advise against shifting into reverse on the track. Or perhaps this is some trick that others know and I don't, which would explain my high lap times... On a serious note, I put redline in the trans of my '97 M3 a month or two after purchasing it. I thought it was smoother immediately after doing the job, but I think that was oil goggles (like beer goggles, get it? Ahh, nevermind. I'll keep the day job.)

My current 3.73:1 LSD is noisy. Could be a bearing. Could be gears. Who knows? Who cares? I decided to fix the noise (goal 1) and change gear ratios (goal 2) at the same time. But I never would have pursued goal 2 if not for the need presented by goal 1. Too hard to justify to the S.O. I have often run shorter tires for autocrossing. Nothing new here, been doing it since my 1st BMW (now on my 5th and 6th). Counting the teeth requires opening up the case. Why not just make marks on the input and output flanges and count the rotations? Finally, it seems there are a lot of people who represent the diffs they're selling as something other than what they are. I can't speak to the motivations of the person who sold you yours. But the guy who sole me mine is in some BMW parts-type of business and should certainly have known better.

I had gone from stock BMW liquid to MTL to D4ATF and now to Mobile 1 ATF. Could hardly tell the four of them apart. MTL rattled a little more than other after hot laps, but that's about it. And those were summer hot laps in Texas on the thinner MTL. Dave, I can't imagine a non-racing scenario where you would cook D4 ATF. Are you sure you don't have something else going on? alex f ------------------------------ Date: Wed, 24 Sep 2003 16:55:44 -0400 From: "Dave Kelley" <[EMAIL PROTECTED]> Subject: RE: [uuc] First time with Redline MTL Hey Jim, Yes, I know that the Redline ATF is a possibility too, but since it is so damn hot on the track down here in the South and never gets too cold, I'm going with James Clay's recommendation of the MT-90. And if I am in fact, having some problems with the synchros, then the thicker fluid should help some too! This car doesn't see too much street time anyway!

I have to try to maintain my dignity in the Instructor Run Group trying to keep in sight of people like James Clay in his Speed Challenge Car! :-) BTW, I was not very successful keeping him in sight for long at Road Atlanta last weekend. But you are correct. I do not know that there is not a problem with my transmission that just happened to start when I put in Mobil One ATF! If I am still having problems with the heavier MT-90 then it will be time to diagnose the problem further!

TIA Ryan, If you give the end of the open end 32mm wrench a good whack with a dead blow hammer, the torque of the impact will break the fan clutch nut before the water pump has a chance to move. It may take a few whacks, but that's how pro's do it. alex f ------------------------------ Date: Wed, 24 Sep 2003 16:37:58 -0700 From: "Marco Romani" <[EMAIL PROTECTED]> Subject: RE: [uuc] M50 fan clutch removal questions There is a special tool for this. However, I just use a long thin screwdriver and jam it in-between two of the bolts on the pulley to hold the pulley while loosening the fan clutch. If you're lucky/good you can give the wrench you're using to loosen the nut a good whack with a dead blow or 5lb sledge and the nut will loosen. I've seen it done, but I've never been able to do it remember the fan clutch is left hand threads.
